One beautiful morning of February as I'm busy appreciating the view from our window and get a sniff of good vibes rising in the radiance of the sun, I've noticed this lonely orange flower in the bunch of red flowers. I've checked the stem of this flower if it is connected to the rest, and oh yeah!, it is! How come there's an orange flower in this plant whose breed is to bloom red flowers?!

| Hi there little orange flower! |
Plant's Profile
Before we unfold the mystery of that orange flower, let me discuss to you about this plant.
 |
| Portulaca oleracea aka "Purslane" |
It has fleshy succulent leaves and stems. They look like baby jade plants. The stems lay flat on the ground as they radiate from a single taproot sometimes forming large mats of leaves. It is closely related to Rose Moss, also known as Portulaca grandiflora, grown as a "not so weedy" ornamental.
Purslane is an annual reproducing from seeds and from stem pieces. Seeds of purslane have been known to stay viable for 40 years in the soil. You may find that fact either depressing or exciting. Depressing in the sense that you didn't want it because its a weed, exciting because it gives a colorful effect in your backyard. :)
According to some article it is grown as vegetable in the other parts of the world. It is used as a vegetable source of omega- 3 fatty acids and high in vitamins and minerals. It possesses marked antioxidant activity.
Have time in reading this before you proceed:
Phenotypes are set of observable characteristics of an individual. It is a description of your actual physical characteristics. (example: color of your hair, skin and eyes)
Allele is an alternative form of gene (one member of a pair) that is located at the specific position in the specific chromosome. A pair of allele may be heterozygous or homozygous.
Unfolding the Mystery: "I am that pretty orange among the red ones."
The orange flower of the Purslane plant exhibits an "Incomplete Dominance". Incomplete Dominance is a non-Mendelian law, meaning to say, it is one of the exceptions in Mendel's Law of Inheritance (the others are Codominance and Multiple Alleles).
It is a form of intermediate inheritance in which one allele for a specific trait is not completely expressed over its paired allele. This results in a third phenotype in which the expressed physical trait is a combination of the phenotypes of both alleles. Unlike in complete dominance inheritance, one allele does not dominate or mask the other allele.
Incomplete dominance can be obviously notice in plants that has been cross pollinated or undergo cross pollination.

It is like gohan and trunks (in anime entitled "Dragon Ball Z") combined and become Gotenks, right?
It is also like YOU that have a wavy or gently curled hair caused by your straight-haired mom and a curly-haired dad.
It is like mommy white mouse and daddy black mouse gave rise to baby grey mouse.

It is like mixing milk and strawberry in a shake and taste milk and strawberry at the same time.
How about this purslane below? Is it also an Incomplete Dominance?
The answer is...........
you will find out in the next blog of mine. :)
I hope you learned something. Cheers for knowledge!
